CONTINUOUS LAP-JOINT AND NUT-LOCK.

Specification of Letters Patent.

Patented Jan. 12, 1909.

Application filed. September 12, 1907. Serial No. 392,602.

To all whom it may concern:

Be it known that we, JOHN LEWIS GASH and SAMUEL L. h'lcDAvITT, citizensof the United States, residing at Elmer, in the county of Macon andState of Missouri, have invented a new and useful Improvement inContinuous Lap-Joints and Nut-Locks, of which the following is aspeciiication.

This invention relates to rail-joints, the object being to provide a lapjoint which will decrease the jar and noise caused by the wheels movingover the same.

Another object of our invention is to provide a very simple andeffective device of this character which will securely hold the meetingends of the rail together, and one which will reduce the wear of therolling stock passing over the same.

A further object of our invention is to provide very novel means forlocking the nuts of the joint so that all danger of the saine workingloose is prevented.

A still further object of our invention is to provide a rail joint whichis exceedingly simple and cheap in construction, and one which willsecurely lock the rails together and prevent the same from spreading.

lilith these objects in view, the invention consists in the novelfeatures of construction, combination and arrangement of parts,hereinafter fully described and pointed out in the claims.

In the drawing forming a part of this specification: Figure l is a topplan view of our improved rail-joint. Fig. 2 is a side elevational viewof the same.- Fig. 3 is a section taken on line 3 3 of Fig. 1. Fig. 4tis a section taken on line 4--4 of Fig. l, and Fig. 5 is a detailperspective of a portion of the locking bar. l

In the drawing A and B indicate railsections having their meeting endscut ob- .liquely forming beveled tongues which are provided with squareends forming a joint which will decrease the jar as the train passesover the same. The joint is placed on a chair-plate C adapted to rest ona couple of ties and is provided with a central notch C in one edge, inwhich a down wardly projecting tongue D of an angled fish-plate D isadapted to lit, the fish-plate resting up against the web of the joint-rails and being provided with a series of spaced openings, throughwhich bolts are adapted to pass through the oint and through a fishplateE arranged on the other side, the said plate being provided withopenings registering with the openings of the first men.-k

tioned plate, and having slots E formed in its base for the purposehereinafter fully described. The heh-plates are securely locked togetherby nuts working on the bolts and the 'fish-plates are locked on thechair by spikes which pass through notches formed in the edges of thechair into the ties, the head resting on the base of the fish-plates andsecurely locking the chair on the ties.

Arranged on the fish-plate E is an angled locking bar F which isprovided with downwardly projecting tongues F2 which fit in the Slotsformed in the fish-plate E and is provided with a series of notches Fladapted to lit over the nuts of the bolts and prevent the same fromturning after they have been tightened, the locking bar being securelylocked on the fish-plate by a screw Gr and it will be readily seen thatafter the islrplates have been securely lockedon the sides of themeeting ends of the rail-sections, thelocking bar can be readily securedthereon so as to securely lock the nut, and it will also be seen that byunscrewing the screw it can be read ily lifted off.

From the foregoing description it will be readily seen that we haveprovided a railjoint which is so constructed that the parts can bereadily detached so as to place the meeting ends of the rails in placethereon, and one which is very strong and durable so that all danger ofthe rails spreading at the joints is prevented.

Having thus fully described our invention, what we claim as new anddesire toV secure by Letters Patent is l. A rail joint comprising achair-plate having a notched edge, fish-plates arranged on said chair,one of said fish-plates being provided with a tongue adapted to iit insaid notch and the other with spaced slots, and an angled locking bararranged on the fishplate With the slots provided with tongues fittingin said slots, for the purpose set forth.

2. In a rail joint, the combination with a chairplate having a notchededge, of railsections having interlocking ends, arranged on saidchair-plate, fish-plates arranged on said chair-plate against the websof the railsections and secured thereto by bolts, one of said{ish-plates being provided with a tongue fitting in the notch of saidchair, and the other with slots, and an angled locking bar provided witha series of notches to receive provided with tongues fitting into saidslots, and having a series of spaced notches adapted to fit over thenuts of the bolts, and means for locking said angle-bar on said 15 thenuts of said bolt arranged on the fishplate With the slots havingtongues projecting into said slots, and secured thereon by a screw, forthe purpose described.

5 3. In a rail joint, the combination with a plate, for the purposedescribed.

chair-plate of rail-sections having beveled JOHN L GASH interlockingtongues arranged on said chair, S L M015 AVITT' fish-plates arranged onsaid chair and bolted to said rails, one of said iisli-plates beinglVitnesses:
